Published on December 19, 2025

The Cardinals outrighted Koperniak to Triple-A Memphis on Friday.

While no longer on the 40-man roster, Koperniak will remain in the organization after passing through waivers unclaimed. The 27-year-old outfielder is coming off a poor 2025 season at Memphis, slashing .249/.322/.387 across 537 plate appearances.
